Expertise

Computer Science

AI

  • This is the development of computer systems that can perform tasks usually requiring human intelligence, such as visual perception, speech recognition, and decision-making

Impact of Artificial Intelligence (AI)

  • Enhances productivity by automating repetitive tasks
  • Improves decision-making through data analysis and pattern recognition
  • Can be used in various industries, such as healthcare, finance, and transportation
  • Raises ethical concerns, including job displacement and privacy issues

VR & AR

  • Virtual Reality (VR):
    • A computer-generated simulation of a three-dimensional replicated environment
    • It can be interacted with in a seemingly real or physical way
    • Can manipulate objects or perform a series of actions
    • Makes use of the sensory experience
    • Uses a virtual reality headset with built in speakers
    • Can be used with gloves / controllers / driving wheel
  • Augmented Reality (AR): A technology that superimposes a computer-generated image or information onto a user's view of the real world, providing a composite view

Impact of Extended Reality (VR and AR)

  • Virtual Reality (VR) immerses users in a simulated environment, while Augmented Reality (AR) overlays digital information onto the real world
  • Used in gaming, education, and training for a more engaging experience
  • Can be applied in fields like architecture, medicine, and retail for improved visualisation and interaction
  • Potential issues with addiction and excessive screen time

Worked example

Some smartphones connected to the internet can allow the user to point their phone’s camera at an object or image to display information about it on the phone’s screen. The object acts like an item in a search engine. This is called augmented reality.
One example of its use is in mobile games, where the user tries to catch characters from the game as the characters appear to walk in the streets. Explain, using examples, other ways in which augmented reality could be used in everyday life.

[4]

Max three of:

Gather information [1]
Can be used as a direction finder [1]
Visualise what something will look like in real life [1]
Could be used for facial recognition [1]

Max three of:

Examples of gathering information about a building/painting / product [1]
Giving information about the area you are moving in / finding your way in an airport/railway station / shopping mall etc. [1]
Used by archaeologists / architects / interior designers / try on clothes / trying makeup/colour of clothing / placing furniture [1]

point it at a word to link to the thesaurus / get it's meaning / translation / modern landscape [1]
Used by the police to recognise suspects [1]

Exam Tip

  • Don't get mixed up between augmented reality and virtual reality - augmented reality changes the real world in front of you (e.g. Pokemon Go) whereas virtual reality puts you in a new world entirely and you can't see the real world around you
